rishi should get to know about tanuja not being pregnant first and then tanuja is tanu actually I have an idea what if while rishi is driving tanuja may mistakenly call him and he would not pick up...but then he may pick it up thinking der might be sumthing related to raaj...so he picks up the call and on the other hand tanuja is wid smiley asking about her decision of marrying sumone else...like she confronted in precap same way after kc celebration and then smiley would speak up the truth...on the other hand rishi listens everything and then he gets happy thinking that tanuja didn't betrayed him...and then he may link up tanuja's sacrificing nature wid tanu...manpreet's words eco in his mind...and at d same tym he reaches to kali maa temple there he gets confident that tanuja is tanu...and starts to leave for home in hurry to meet tanuja and ask forgiveness and meanwhile he meets wid accident... this might happen in order to make rishi aware about pregnancy truth as well as tanuja being tanu... and afterwords don't know memory loss track will happen or not...but in case if it doesn't take place that can show afterwords getting normal rishi teams up wid tanuja uniting smiley wid her bf and at the same tym starts to collect valid proofs of tanuja being tanu... this is my imagination...and I guess if they go like this way many misunderstandings will get solved...and story will move in right direction...
